Question

我试图在图片拖动后更新输入框的值。以下是fiddle和代码。

我需要在dragsort后手动点击图片来更新$（'＃pic'）。val（）如何跳过手动点击？或者它是一种自动点击“li”的方式？

我尝试过ul.children（'li'）。first（）。click（）但它也没有用。

        input_id = ul.attr('id').replace('v_','');

        console.log(switched_input_value);

可能是您正在寻找的东西。您无需触发click，也无需将click事件绑定到$('.sortablelist li')，只需使用dragEnd事件

$('.sortablelist').dragsort({
      dragSelectorExclude: 'input, textarea, a[href] , i , em',
      dragBetween: true,
      placeHolderTemplate: '<li style="font-size:18px;"><div style="padding-top:50px;">moving...</div></li>',
      dragEnd: function() {
         getData();
      }
    });

function getData() {
    var listName = [];
    $('.sortablelist').find('li').each(function() {
        console.log($(this).find('h5').html());
        listName.push($(this).find('h5').html());
    });
    $('#pic').val(listName.join(','));

}
